4K RESOURCE UNAVAILABLE

Yesterday we received an error in DB2 saying
DSNT501I -DB2P DSNIWKFL RESOURCE UNAVAILABLE 376
CORRELATION-ID=ENTRTP700003
CONNECTION-ID=CICS***
LUW-ID=*
REASON 00C90084
TYPE 00000230
NAME 4K
This was caused because Temporary 4K Dataset became full and could not create an extent. We allocated a new dataset for 4K to resolve the issue.
But my query is how can we ascertain that which query or operation caused this failure. Can somebody please shed some light on this issue.

In the CORRELATION-ID value, characters 5-8 identify the CICS
transaction involved. From that, you can issue a CEMT I
TRAN(TP70) within the CICS region to determine the program being
executed. And from that you can eventually isolate the SQL
causing your 4K datasets to fill.
